Application filed 29, 1924. Serial nu. 716,782.

To all whom it may concern:

Be it known that I, Hummer .AUBURN, a citizen of the United States of America, and resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Hinge Structures for LooseLeaf Devices and the like, of which the following is a specification. a

My invention relates to hinge structures such as are applied to loose leaf devices for securing cover members to the pagebinding mechanisms. I

An object of my invention is to provide a hinge structure that is simple of construction.

Another object is to provide a device of this kind that may be economically manufactured and easily assembled, thereby effecting a substantial saving both in material and labor.

These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:

Fig. 1 is a perspective view ofa loose lea-f device having embodied therein a hinge structure of my invention.

Fig. 2 is a cr'oss'sectional view taken on line Q Qof Fig; 1.

Fig. 3 is across sectionalview on line 33 of Fig. 2.

The binder ,5niay be of the ordinary type such as arelocked and opened by means of a key, or of any other desired type. The leaf binding mechanism consists of a flat fixed binder member 6 carrying" bi'nder posts 7 on one of its flat sides. In the present construction both the lower binder member 6 and upper binder member 8 consist of tubular housings,- theupper tubular housing 8 having any of the usual locking means disposed within the bore therein. Plugs 9 having' body portions 10 adapted to fit snugly into the open ends of the tubular housings 6 and 8 are provided with flanges 11 which abut the ends of the housings. Each plug carries a recess 12 disposed along one side of the body portion 10 thereof and said recess also extends into the flange 11 disposed without the housings 6 and 8. A hinge plate 13 is provided with a substantially tubular way or bore 14 which may be formed by turning the end of the plate 13 upon itself as is common in the manufacture of sheet metal hinges. The tubular portion 15 of the plate 13 may extend throughout the length of the plate 13 as shown in Fig. *2, or a section of the" tubular portion 15 may 7 be formed along the edge of the plate 13; adjacent one end thereof. The cover 16 is secured to the plate 13 by any of the usual expedients such as inserting a number of small rivets through the cover 16 and through the holes 17 in the plate 13. The cover 16 is hingedly mounted on the tubular housings 6 and 8 by means of 'U-shaped hinge pins 18 having arms 19 and 20. The arms 20 are disposed within the tubular passage 14 on the plate 13 while the arms 19 are disposed within the tubular housings 6 and 8 adjacent the wall thereof. The pins, when in this position, preclude separation of the tubular housings and the plates The plugs 9 are then inserted into the ends of the housings 6 and 8, the recess 12 accommodating the arm 19' and the adjacent shoulder portion of the hinge pin 18. The plugs'9' are preferably made of a fairly soft metal so that after being positioned as shown in Fig. 2, the wall of the tubular housings 6 and 8 may be indented as shownat 21,;se'e

Fig. 3,"by means of a punch or the like,

thereby securing the plugs in position against removal. It has been found in pract-ic that the'plugs 9 willgi-vesatisfactory results if made-of aluminuln The hinge pins and plugs having been positioned "as. shown in Fig. 2-,it will be observed thatthe flange portion 11 of the plug 9 precludes lateral movement of the hinge pin 18 and that thetwo arms of'the hinge pins preclude separation of the hinge plate and thetubular housing whereby a simple-and economical hinge structure has been provided. The length of the arms of the hinge pins may .OfCOllISG-lJGf varied, and thetubular portion 15 of the plate 13 may also be loonstructed of just sufficient length to accommodate the length of the arm 20 to be disposed therein, or a series of lugs may be struck from the plate 13 for the purpose of retaining the arm 20.

While in the accompanying drawings, I have shown one particular disclosure of my invention, it will be readily apparent V to those skilled in the art, that various modifications may. be adapted to produce a structure within the scope of this invention. The tubular housin 6 or 8 may be considered as one hinge plate and plate 13 as the complementary hinge plate, so that it will be observed that this structure may well be adapted to other uses.

What I claim is:

1. In a device of the class described the combination of a tubular housing, a hinge plate having a bore extending along one edge thereof, a U-shaped hinge pin having its one arm disposed within the housing and its other arm disposed within the bore in the hinge plate, and a plug insertible and retained in the housing adapted to eo-operate with the housing for precluding the longitudinal and lateral displacement of the hinge pin. V

2. In a device of the class described the combination with a pair of hinge members having longitudinal openings extending along their adjacent edges, a pair of U- shaped hinge pins having their arms disposed within the openings in the members, and a plug secured in the opening at each end of oneof the members and co-operating with the wall of the said member for precluding the longitudinal and lateral displacement of the hinge pin.

8. In a device of the class described the combination of a pair of hinge members hav- "ing longitudinal openings extending along their adjacent'edges, a U-shaped hinge pin having its arms disposed within the openings in the members, and a plug in the end of one of the hinge members, said plug being recessed to accommodate the arm of the lateral displacement of the hinge pin and the plug having a shoulder formed at the end of the recess for precluding the longitudinal displacement of the said hinge pin.

. 5. In a device of the class described the combination of a tubular housing, a hinge pin comprising an arm and a base portion angularly disposed one tothe other, the arm insertible into the bore in the tubular member and a plug for sealing the bore in the tube, the plug having a recess extending longitudinally of the plug and disposed at the surface of the plug, the recess being of a size to receive the arm and to restrain the arm from lateral movement, the plug comprising a shoulder extending over one end of the recess for restraining the arm from mlovement longitudinally of the recess in the p ug. v

6. In a hinge pin and mounting the combination with a hinge pin comprising an arm and a base portion extending therefrom at an angle, of a tubular housing and a plug comprising a body and a flange at one end of the body, the body being insertible into the bore of the tubular housing and the flange engaging the edge of the housing for limiting movement of the plug into the housing, the plug body having a recess along its surface and for which recess the tubular housing forms a cover, the recess extending into the flange to a distance substantially equal to the cross section of the hinge pin whereby the base of thehinge pin may extend from the recess in the plug body and be flanked on opposite sides by the housing and the flange for precluding movement of the hinge pin longitudinally of itself.

7. In a device of the class described the combination of a tubular housing, a plug secured in the end of the housing comprising a body portion, a separable hinge member insertible between the body of the plug and the wall of the housing and retained in'position by the plug, and a hingeplate connected with the hinge member.

8. In adevice of the class described the combination of a tubular housing, a U- shaped hinge pin comprising arms, a plug for retaining-the one arm of the hinge pin in the tubular housing, and a hinge plate connected with the second arm of the hinge pin.

In testimony whereof, I have hereunto subscribed my name this 24th day of May,

HUBERT AUBURN.
